ALBANY, N.Y. — The autopsy results for a man who died while in custody, following an incident involving New York prison guards, have been classified as homicide, according to the family’s attorneys on Wednesday.

The report from the county medical examiner’s office states that Robert Brooks passed away in December due to neck compression and several blunt impact injuries. Lawyers representing his family have confirmed that the autopsy determined the death to be a homicide.

Footage recorded from body cameras captured a lengthy incident in which correctional officers attacked Brooks for nearly ten minutes while he was restrained on a medical exam table at the Marcy Correctional Facility on December 9. The video shows one officer striking Brooks in the abdomen using his shoe, while another officer aggressively pulls him by the neck before forcefully dropping him back onto the examination table.

Brooks was officially declared dead the following morning.

Family attorney Stephen Schwarz remarked that the autopsy report dispels any claims suggesting alternative causes of death apart from what was documented on the video.

In response to Brooks’ death, New York’s attorney general has appointed Onondaga County District Attorney William Fitzpatrick to serve as a special prosecutor overseeing the investigation. A grand jury is anticipated to review the case’s evidence soon.

In the wake of the incident, over a dozen correctional officers and two nurses have been suspended without pay, and one officer has chosen to resign.

Robert L. Brooks Jr., the son of the deceased, has filed a lawsuit against those involved in the assault, including the administration of the facility at the time and the commissioner of the state Department of Corrections and Community Supervision.
